Summary by cubic

Added invokable skill slash commands and new commands to list and import skills, making skills easier to discover and run from the CLI.

• New Features

  • Skills are invokable via generated slash commands (skill-<name>, slugified) from Markdown skills under ~/.continue/skills or .claude/skills; invoking routes to the Skills tool and sets skill_name automatically.
  • /skills lists all skills with name, description, and path (shows a helpful message if none found).
  • /import-skill <url-or-name> prepares a guided prompt to fetch and save skills into ~/.continue/skills/<skill-name>, with user confirmation.
  • Skills tool allowed by default in permissions (default and plan modes).

• Refactors

  • getAllSlashCommands is now async; UI (SlashCommandUI, UserInput) loads commands asynchronously and avoids stale updates on unmount; integration tests updated to await command loading.

^{Written for commit c1a6f80. Summary will update on new commits.}
